Jair Jurrjens tweaked his right knee during a bullpen session Friday night and chose not to inform the Braves of the discomfort until it lingered into Saturday. The 24-year-old right-hander showed some improvement with his mobility Sunday.

Jair Jurrjens’ sore knee led the Braves to summon prospect Brandon Beachy to Philadelphia in case he was needed to make his major league debut with an emergency start Monday night against the Phillies.
